CARPET-SWEEPEB.

Specification of Letters Patent.

Patented April 6, 1909.

Application filed August 1'7, 1904. Serial No. 221,001.

To all whom it may concern:

Be it known that I, LEWIS P. HALLADAY, a citizen of the United States,residing at Streator, in the county of Lasalle and State of Illinois,have invented a certain new and useful Improvement in Carpet-Sweepers,which the following is a specification.

lv'ly invention relates to carpet sweepers, and has for its object toprovide a new and improved device of this description.

My invention is illustrated in the accompanying drawings, wherein Figure1 is an end View of a carpet sweeper; Fig. 2 is a sectional view takenon line 22, Fig. 1; Fig. 3 is a View of the hearing protecting device,as seen from below.

Like letters refer to like parts throughout the several figures.

Referring now to Figs. 1, 2 and 3 I have shown what may be termed abearing protecting device for carpet sweepers. In the ordinary carpetsweeper the ends of the brush shaft become wrapped with ravelings,threads, hair, and the like, and these ravelings soon interfere with theoperation of the brush. This has been one of the serious difficultiesmet with in practice.

One of the objects of my invention is to obviate this diiiiculty, and Ido this by providing what I have termed a bearing protecting device. Asherein shown, this device consists of an inclosing device A whichincloses the end of the brush shaft A, and which is stationary duringthe operation of the sweeper, this preventing material from becomingwrapped about the ends of the shaft. This inclosing device is providedwith openings at the sides, as shown at A through which the periphery ofthe wheel. on the end of the brush shaft projects at each side so as tomake contact with the main wheels B of the sweeper. This inclosingdevice is preferably provided with an inwardly proj cting part A whichfits into an opening in the brush shaft or the Wheel at the end thereofso as to form a bearing therefor. Said inclosing device tits tightlyagainst the casing of the sweeper at the top, and is preferably arrangedso as to project inwardly past the end of the casing at the bottom, asshown at A there being provided grooves or slots A, as shown in Fig. 3,for the edges of the casing on each side of the slot O in the end of thecasing. This construction stiffens the case and makes the entireconstruction more rigid. The inclosing device A is arranged so as to beheld in position by the end band D which extends across the end of thesweeper. Any suitable means for this purpose may be used. As hereinshown, the inclosing device is provided with a groove or the like A intowhich fits the end band D. The faces of the inclosing device leading tothis slot, are preferably beveled, as shown at A, so that the inclosingdevice may be readily forced into position beneath the end band, andwhen in position will be secured thereby.

When it is desired to attach the brush to the casing the bearingprotecting device is placed at each end of the brush shaft, and then thebrush is pushed up into position through the slot O, the beveled faces Aforcing the end bands outwardly so as to permit the passage of thebearing protecting devices, said bands springing back into po- 1 sitionin the grooves A when they come 0pposite such grooves. These end bandsthus keep the anti-raveling device and the brush in proper positionduring the operation of the sweeper, the brush shaft rotating about theprojections A which act as bearings. It will be seen that by means ofthis construction the ravelings, threads and the like cannot becomewrapped about the ends of the brush shaft, because such ends areprotected, and consequently the evils resulting from such material areobviated. These bearing protecting devices are preferably stamped out ofsheet metal.

I have described in detail a particular construction embodying myinvention, but it is of course evident that the parts may be greatlyvaried in form, construction and arrangement without departing from thespirit of my invention, and T, therefore, do not limit myself to theparticular construction shown.

I claim:

1. A carpet sweeper comprising a case, a rotatable brush in the casehaving a shaft with a wheel mounted thereon, an inclosing end pieceextending over said wheel and provided with a projecting part whichprojects into an. opening in the shaft so as to act as a bearing, an'end band extending across the end of the carpet sweeper and separatedtherefrom by a space, said inclosing end piece adapted to pass betweenthe j case and the end band and provided with a groove into which saidend band fits so as to hold said inciosing end piece in position. Acarpet sweeper comprising a case, a rotate hie brush in the case, thecase having an opening in the end for the brush shaft, an inciosing endpiece fitting over the end of the brush shaft and provided with an in*ardiy projecting part having slots at each side into which are receivedthe edges of the sweeper case. in a carpet sweeper, the combination of acasing with wheels on the outside of such casing, such casing having aslot, z. b'nsh roii projecting through the slot and f l i i I I ibetween the wheels so as to be driven thereby and a removable protectingcap piece on which the roll is journaled, inclosing the end of suchroll, such cap piece being cut away so as to allow the Wheels to comeinto contact with the roll, and a flexible hand at the end of the casingenga ing with the cap piece to hold such cap piece and roll in position.
